Evaluates and writes the turbulence intensity field 'I'.
The turbulence intensity field 'I' is the root-mean-square of the turbulent velocity fluctuations normalised by the local velocity magnitude:
![\[ I \equiv \frac{\sqrt{\frac{2}{3}\, k}}{U} \]](form_127.png)
To avoid spurious extrema and division by 0 I is limited to 1 where the velocity magnitude is less than the turbulent velocity fluctuations.
Example of function object specification:
functions
{
.
.
.
turbulenceIntensity
{
type turbulenceIntensity;
libs ("libfieldFunctionObjects.so");
}
.
.
.
}
or using the standard configuration file:
functions
{
.
.
.
#includeFunc turbulenceIntensity
.
.
.
